A portion of Santiago Calatrava’s $4 billion PATH station has opened. According to NY Daily News, the Western Concourse will now relieve New Yorkers from “cramped sidewalks and temporary bridges” crossing West St. with a 600-foot underground passage lined in “bright white marble” that connects the World Trade Center to the neighboring office complex formerly known as the World Financial Center. Once complete in 2015, the controversial transit hub will double as a massive shopping and retail complex, which aims to “transform” the cultural experience of lower Manhattan.
